The results indicated that the high-temperature creep life of the material improved by more than 70% following GBE treatment. Electron backscatter diffraction and nano-indentation analysis showed that the creep stress concentration at coherent twin boundaries (CTBs) is lower than that at random grain boundaries, reducing the likelihood of creep voids or cracks forming at CTBs. Furthermore, CTBs have a suppressive effect on the propagation of grain boundary cracks.
